Description

A kind of eurotium cristatum tea automation zymotechnique
Technical field
The present invention relates to tea processing field, and in particular to a kind of eurotium cristatum tea automation zymotechnique.
Background technique
In recent years, Fu-brick tea is because of its unique quality characteristic and health-care efficacy, by the favor of the majority of consumers, and its institute Distinctive golden flower bacterium has become the hot spot that everybody pays close attention to and studies.Studies have shown that in Fu brick golden flower growth, significantly affect tealeaves The variation of internal substance ingredient generates a series of metabolic enzymes, such as cellulase, polyphenol oxidase during golden flower bacterium floating, Make tealeaves internal substance that hydrolysis, conversion, oxidation, polymerization occur, forms the beneficial substance of a series of pairs of human bodies, promote tealeaves product Matter.Meanwhile golden flower bacterium itself has lipid-loweringing, antibacterial, antitumor, anti-oxidant and other effects, and can secrete some special functions Active constituent.
Currently, the separation for golden flower bacterium identifies that the research of artificial infection, new product development etc. is relatively more, and first Afterwards using raw materials such as golden flower bacterium fermentation white tea, oolong tea, loose teas, different vegetable materials furthermore are inoculated in about golden flower bacterium The relevant report of middle growth, but eurotium cristatum tea zymotechnique is more complicated at present, and multipurpose high-pressure wet sterilization in feedstock processing makes Tealeaves after must fermenting has steam taste, influences mouthfeel, while fermentation process is easy to cannot achieve industrial metaplasia by living contaminants It produces.
Summary of the invention
In order to overcome the above problem, the purpose of the present invention is to provide a kind of eurotium cristatum teas to automate zymotechnique, the work Skill uses microwave disinfection, and eurotium cristatum tea obtained is avoided to generate steam taste;The air being passed through in fermentation process simultaneously is by filtering Processing effectively solves the problems, such as living contaminants;Control temperature and humidity is golden flower bacterium suitable growth temperature, is mushroomed out conducive to golden flower bacterium, Effectively shorten the production cycle, the eurotium cristatum tea for completely draping over one's shoulders golden flower can be obtained in 3 ~ 5 days in fermentation, and fermentation process is in a device It is completed in container, fermentation process can realize automation control.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
A kind of eurotium cristatum tea automation zymotechnique, comprising the following steps:
1) preparation of golden flower bacterium tea powder: isolating golden flower bacterium from Fu-brick tea first, and purifying culture dissipates after being inoculated in sterilizing Floating in tea obtains the good eurotium cristatum tea of floating, is crushed after dry up to golden flower bacterium tea powder;
2) loose tea is spraying: by loose tea impurity elimination, normal-temperature water spraying treatment;
3) get damp again: the loose tea moisture after spraying can not diffuse to inside tealeaves rapidly, and resurgence process makes loose tea table Inside the moisture diffusion to tealeaves of face, resurgence after a certain period of time, can make loose tea moisture distribution uniform;
4) microwave disinfection: the loose tea after spraying and dampening carries out microwave disinfection processing;
5) inoculation and floating: powdered golden flower bacterium tea powder is uniformly dissipated into the loose tea surface after sterilization, it is suitable to control Temperature and humidity carries out floating culture;
6) dry: the loose tea after floating carries out microwave drying.
Further, sprayed through nozzle for normal-temperature water by spraying described in step 2, spraying water consumption be loose tea quality 20% ~ 25%。
Further, resurgence time described in step 3 is 2 ~ 3 hours.
Further, microwave disinfection described in step 4) is interval sterilization, and sterilizing power 2000w is sterilized every 1min 10s, 3 ~ 5min of sterilizing time.
Further, golden flower bacterium tea powder described in step 5) is to overwork the loose tea crushing gained of golden flower bacterium, and additive amount is The 3% ~ 5% of dry tea.Yellow particle is overworked on floating to loose tea surface, and floating controls humidity 60% ~ 70%, 24 ~ 30 DEG C of cultivation temperature, trains 3 ~ 5 days time is supported, until golden flower is overworked on loose tea surface;And open device blow vent, it is passed through filtered air.
Further, drying described in step 6) be microwave drying, microwave dehydration efficiency by 0.8 ~ 1kg/ kilowatts/when Meter determines dry power, loose tea moisture content 5% ~ 7% after control is dry according to the practical dehydrating amount of loose tea.
Further, the fermentation technology process is completed in an installation for fermenting, and the installation for fermenting includes shell 21, the top and bottom of the shell 21 are respectively arranged with upper and lower blow vent 110, and the top of shell 21 is fixedly installed with warm and humid Sensor 2 is spent, injection spray pipe 3 is fixedly installed on the rear wall of shell 21, multiple supporter gauzes 17, shell is fixed in shell 21 It is fixed with dust box 4,6,8,11,13,15 and microwave tube 5,7,9,12,14,16 in 21 left and right sidewall, is fixed on shell 21 Installation for fermenting door 22 is installed, the middle position of installation for fermenting door 22 is fixed with observation window 18, upper right side be vertically fixed with it is micro- Type computer control screen 19, lower right side are fixed with control switch 20.
Compared with prior art, the invention has the following beneficial technical effects:
Resurgence processing loose tea, can make moisture distribution in loose tea uniform, and without high-temperature process after the present invention uses by spraying Process reduces the loss of nutritional ingredient in tealeaves;
Microwave disinfection handles loose tea, and compared to high pressure steam sterilization, sterilising temp is low, and sterilization time is short, to having in loose tea It is small to imitate composition influence, and eurotium cristatum tea obtained, without steam taste, organoleptic quality is preferable;
It is spilt into loose tea using golden flower bacterium tea powder by air blast, golden flower bacterium powder in loose tea can be made to be evenly distributed, be conducive to loose tea Floating is uniform;
It is golden flower bacterium suitable growth temperature that temperature and humidity is controlled during floating, mushrooms out, effectively shortens conducive to golden flower bacterium The eurotium cristatum tea for completely draping over one's shoulders golden flower can be obtained in 5 days in production cycle, fermentation;
And fermentation process is completed in an apparatus container, and fermentation process can realize automation control, easy to operate, Conducive to industrialized production.
